How do i predefine a flag in sharedPreferences?

Question

I want to define a flag in android sharedPreferences to check whether a service is running or not, but it can't be at runtime, so is it possible to do it somehow in xml? also, is there anyway that i can check whether a service is running or not?

I don't get why you can't define a flag for SharedPreferences, but if you want to check if service running you can create global variable and check it:

public class MyService extends Service {
        public static boolean sIsRunning;


        @Override
        public void onCreate() {
            super.onCreate();
            sIsRunning = true;
        }

        @Override
        public void onDestroy() {
            super.onDestroy();
            sIsRunning = false;
        }
    }

Or check running services with ActivityManager:

private boolean isMyServiceRunning(Class<?> serviceClass) {
    ActivityManager manager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
    for (RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE)) {
        if (serviceClass.getName().equals(service.service.getClassName())) {
            return true;
        }
    }
    return false;
}
